Glass fibers with a light beam width of 25°, 30° and 66° are used to manufacture Philtec sensors.
The narrower beams give longer ranges. The standard cable length is 90 cm.
25° fibers can be used in continuous lengths up to 3 meters.
30° fibers can be used for continuous lengths up to 9 meters.
66° fibers can be used for continuous lengths of up to 15 meters.

Vacuum sensors are ideal for wafer spacing and position measurements in vacuum. They represent a powerful low-cost alternative to laser interferometry.
Reflection-compensated RC sensors for applications in which the target is rotated or moved out of the sensor area.
All sensors can be manufactured according to customer specifications.
For applications in which the measurement object moves along the sensor axis.
D sensors provide an output signal that is proportional to the distance and reflectance of the object surface. The output function provides two usable operating ranges: In near side operation, the highest resolution is achieved, while at far side the distances high sensitivity is available in a larger working range.
Areas of application for D sensors are, for example:
Motion detection of the actuators
Vibration in the ball bearing
Deflection of the membrane
Distance measurement in liquid
Dynamic inspection on the fuel injector

RC models (Reflectance Compensated) are used for translating and rotating targets, where the target reflectance is variable. The RC type sensor is a more general purpose optical sensor that can make accurate distance measurements to rotating or translating targets as well as measure part-to-part size variations in production parts.
Principle of Operation: These are retro-reflective optical devices. The sensors use bundled glass or quartz fibers to transmit light to and receive reflected light from target surfaces. The intensity of the reflected light is processed to provide the distance between the sensor tip and a target surface..
